Blue Box – Officially Woz

I used a DOS program called blue beep to try it in the early 1990s. Got the famed kerchunk noise once, but was unable to get any further.

Even by 1993 electronic switching was replacing the kinds of old analog systems you could do this with.

This article is from 2018 and he implies that it can still do something. That would be shocking. Maybe there are still systems around that respond to 2600 in some way for legacy reasons... I do know that there are some ancient switches here and there but that old?

This is pretty much the same story Woz has in his autobiography 'iWoz'. Really funny to read, especially for engineers who cannot make that much sense of the whole management thing.
